[lib][web][native] Refactor setDeviceToken action

Summary:
issue: https://linear.app/comm/issue/ENG-5284/refactor-setdevicetoken-action
I split the action into two actions to spare the calling code having to select all keyservers when it simply wants to call all of them

Test Plan: tested that both action work, tested that
